oh i'm not letting you call yuyu hakusho a near perfect series. It had CONSTANT tonal shifts, inconsistent characterisation, plots that were either exceedingly generic (tournament), or exceedingly generic and cut off because togashi was done with it (second tournament in demon world)
the series had many cool moments (black chapter), but was one of the least perfect, most schizophrenic series ever.
near perfect. pah.
also beelzebub is pretty much... nothing like it, so i'll agree with you that much
